To all whom/it may concern:

Be it known that I, 'lno ms R. Baown, a at the city, county, and State of New York, have invented a certain new and useful Improvement in Tank-Cars, of which the following is a full, clear, and exact description, such as i will enable others skilled in-the art to which ll appertains to make and use the same, ref

erence being had to the accompanying drawings, forming part ct this speciiicatlon, m which Figure 1 is a side elevational view, partly invertical section, of my improved tank-car. Fig. 2 is a cross-sectional view on the line 2 2 of Fig. l, and Figs. 3 and 4 are crosssectional views illustrating modified forms of my improved tank-car.

This invention relates to a new and useful improvement in 'talnk-oars,the objectbeing to construct a car in which the plate forming the bottom Wall of the tank constitutes the main sup orting niembenthe same extendmg from Another feature of my invention consists in dispensing with a center sill and utilizing the bottom plate of the tank as a mediunr through which the buffing and pulling stresses are transmitted. l

In the drawings, 1 indicates the bottom late of the tank, which, as shown, extends from end to end of the tank, although said bottom plate could terminate at the bolsterpoints, if so desired. lhis bottom plate referably made of material su'fiiciently lieavy to carry the weight im. :osed upon it and is reinforced by a longitudinal centrallyarranged troughdlk'e depression madadeen est at'its middle and tapering thence toward its ends. This reinforcing. enlargement makes the tank non-circular in crossseotion and likewise provides a -"'"sump through which the contents of the tank may il'rair. tothe discharge-valve 3,. The side edges of this supporting-plate may be flanged, as

shown at 4, for the purpose of adding strength, and to these flangedsde edges may be riveted strengthening members 5, (see- Fig. 3,) the ends of whi h may be connected to the bolsters and the lower edges ct which may be connect-ed to plates 7, whose inner edges extend inside of the tank, as shown in Fig. 4;. This plate 1 may also be reinforced by angles 8, extending longitudinally and se--. cured to said plate on each side of thetroughshaped reinforcing depression, as shown in Figs. 2, 3, and 4. l

9 are the circumferential plates forming the side and to telescopical y engage each other and are riveted together and to the longitudinal edges of the plate 1.

10 are the tank-heads, which may beof usual construction.

11 is the rail.

13 indicates the fillin dome.

14 (see Fig. 2) is the bolster, preferably in. the form of a casting, or the same may be made of pressed structural steel, said casting being provided with draft members 15, in which the draft-rigging may be supported.

in Fig. 4 the circumferential sheets constituting the side and. top members of the tank are secured at their lower longitudinal edges by means oi. outwardly-turned flanges, through which the scouring-rivets are passed.

From the above description it will be seen that my improved tank-car requires no un deri'rame, as the bottom plate of the tank itself serves as a support -l'or the lading, in addition to which, by reason ofthe trough like reinforcing depression and its side flanges, it is made sufficiently strong to re sist torsional as well as bufling and pulling stresses.

Having thus described the invention, what footboard, and 12 is-the hand- I am aware that minor changes in the conwalls of the tank, whose edges is claimed as new; and desired to be secured by'l etters Patent, is-

1. In a tank car, a tanksheet or plate havinga longitudinally-disposed t1pugl1-like depression, and longitudinallyd1s deed rein forcing-flanges; substantially as escribed.

2. In a tanlccar, a tank sheet or plate hav ing a longitudinally-disposed trough-like depression at its center and having its edges l flanged to add stiffness to the structure; submay be reiniorced by angles 6, or said flanges stantially as described.

continuous from end to end of the car and forming a medium. through which bulling and pulling stresses are transmitted; subs tuntizilly as described.

6. In a tank-car, a bottom sheet or plate sees-es extending from end to end 01 the car forsupporting the hiding end forming a medium I through which buffing or pulling stres -vs are transmitted, and tank-sheets forming to 1;"

and. side walls of the tank which are to said. bottom scribed.

In testimony whereof I hereunto X my signature, in the presence of two Witnesses, this 20th day of November, 1906.
